In an audio commentary for "Regeneration" on the ENT Season 2 Blu-ray, Friedericy and Billingsley joked that Friedericy got the part of Rooney by sleeping with Tucker actor Connor Trinneer. In reality, Friedericy auditioned for the role of Rooney, but when she walked into the room to audition, Star Trek: Enterprise creators and Executive Producers Rick Berman and Brannon Braga pretended not to know her. "It was very unnerving, because I'm very shy and I didn't know whether I should say hello or not," Friedericy explained. "So, I sort of waved at them and they both kind of looked distastefully at me, and looked up at the ceiling and then they said, 'Go,' and I thought I wasn't gonna get it, and it was sad, but then I got the call and I got it."

On the set, Friedericy was referred to as a Borg baby. "I was called the baby Borg because Borg are never little, and I'm five-foot-three," she remarked. Applying the Borg makeup to Friedericy for Rooney's assimilated appearance took five-and-a-half hours. This was longer than usual because the makeup team, not having done any Borg for a while, initially made a mistake with Rooney's Borg makeup. To portray the assimilated Rooney, Friedericy also wore a Borg costume that Roxann Dawson had previously wore, in VOY: "Unimatrix Zero". Once Friedericy was made to look Borg, it was time for her to go before the cameras as the assimilated Rooney. Filming the character's death scene didn't require a stunt performer. "I was really pleased with myself," she reminisced, "because they squibbed me [repeatedly], and I did my own stunt." Each time Friedericy performed the stunt sequence, John Billingsley applauded her from off-camera. (ENT Season 2 Blu-ray, "Regeneration" audio commentary)

In an interview, she compared the role of General Beckman to Vaughn Armstrong's role as AdmiralMaxwell Forrest on Enterprise, appearing mostly on a viewscreen to send the main characters on various assignments. [3]

More recently, Friedericy filmed episodes of Impastor (2015), How to Get Away with Murder (2015, with Famke Janssen, Roger Rignack, and Billy Brown), The Friendless Five (2015), and The People V. O.J. Simpson: American Crime Story (2016, with Bruce Greenwood and Michael McGrady) as well as the drama Salt Water (2016, with Deborah Strang) on which she also worked as producer and the thriller Madtown (2016, playing again the wife of real life husband John Billingsley).
